Versuchsvorschrift

Ethyl 6-chloro-2-({2,2,2-trifluoro-1-[3-(trifluoromethyl)phenyl]ethyl}carbamoyl)-1H-indole-5-carboxylate (1.00 g, 2.03 mmol) was dissolved under argon at 0° C. in N,N-dimethylformamide (20 ml). Sodium hydride (60%; 0.079 g, 1.97 mmol) was added and the mixture was stirred while cooling with ice for 2 h. Subsequently, iodoethane (0.15 ml, 1.93 mmol) was added dropwise. The reaction mixture was thawed while stirring within 36 h. Water and ethyl acetate were added and the phases were separated. The organic phase was washed with saturated sodium chloride solution and dried over magnesium sulphate, and the solvent was removed under reduced pressure. The residue was chromatographed with cyclohexane/ethyl acetate (4/1) and gave 0.65 g (64% of theory) of ethyl 6-chloro-1-ethyl-2-({2,2,2-trifluoro-1-[3-(trifluoromethyl)phenyl]ethyl}carbamoyl)-1H-indole-5-carboxylate.
